A kind of temperature controller
Technical field
The utility model relates to temperature controller, and particularly a kind of temperature controller that is widely used in products such as electric cooker, electric pressure cooking saucepan, electric food warmer belongs to the improvement technology to existing temperature controller structure.
Background technology
The temperature controller that uses on the products such as present commercially available electric cooker, electric pressure cooking saucepan, electric food warmer mainly contains two kinds.
First kind of temperature controller structure as shown in Figure 1 and Figure 2; thermal cut-off 10 and thermistor 8 are fixed on the gland 6 by fixed head 1 and internal fixation plate 11; gland 6 is fixed on the outer cup 5; outer cup 5 is fixed by claw and meal pot outer pot; gland 6 moves up and down by outer spring 2; assurance is tight with the interior lightly fried dumpling of product, realizes temperature sense and overheat protective function.But this structure has only thermistor and thermal cut-off, and pot inducing function in not having causes the user in use might forget interior pot is put into products such as meal pot, and products such as electric cooker also can heat; Second kind of temperature controller structure as shown in Figure 3, magnetic red pipe 7 and thermistor 8 are fixed on the gland 6, gland 6 is fixing with outer cup 5, the claw by outer cup 5 is connected with fixed head 1; Magnet 9 is fixed on the outer cup 5; magnetic red pipe 7 is realized moving up and down by spring 2 with thermistor 8, in moving process, and magnetic red pipe 7 and magnet 9 inductions; closing of circuit or disconnection; realize temperature sense and interior pot inducing function, but this structure have only thermistor and interior pot induction pick-up assembly, does not have overheat protective function; the cost price of magnetic red pipe is higher; easily be mechanically damaged, and parts are too much, complexity are installed reduced efficient.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of cost low, and is reliability and durability, and complete function is simple in structure, easily the temperature controller of assembling.
The technical scheme that realizes the utility model purpose is: a kind of temperature controller, comprise fixed head, spring, gland support, Control Component, outer cup and gland, Control Component is fixed in the outer cup by the gland support, outer cup flexibly connects by claw and fixed head, spring is located between outer cup and the fixed head, it is characterized in that Control Component integrated thermistor, thermal cut-off and microswitch three big assemblies.
The contact of described microswitch stretches out in the lower end of Control Component, is fixed with the locating piece that triggers the microswitch break-make on the position of corresponding microswitch contact on the described fixed head.Therefore, in use whether microswitch is under pressure along with spring and moves up and down: in when pot in not having, the Control Component of temperature controller moves up under the promotion of spring, and the contact that drives microswitch leaves locating piece, the microswitch closure; When putting into pot, the Control Component of temperature controller moves down under the pressure of interior pot promotes, and drives the contact contact locating piece of microswitch, and microswitch disconnects.Thereby realize judging having or not of interior pot by the break-make of microswitch.
The beneficial effects of the utility model are; owing to adopt the Control Component that thermistor, thermal cut-off and three assemblies of microswitch is integrated into a part; both integrated temperature sense, overheating protection, interior pot induction three big functions; reduced amount of parts again; simplify the assembling of temperature controller, increase work efficiency, and microswitch is more reliability and durability than magnetic red pipe; cost price is very cheap, has reduced the cost of product accordingly.

Embodiment
As Fig. 4; Fig. 5; shown in Figure 6; the utility model comprises fixed head 1; spring 2; gland support 3; Control Component 4; outer cup 5 and gland 6; Control Component 4 is fixed in the outer cup 5 by gland support 3; outer cup 5 cooperatively interacts by the fixed orifice 11 on three claws 51 and the fixed head 1 and realizes flexibly connecting; spring 2 cover is outside on the cup 5; one end leans cup 5 upper ends outside; the other end leans on fixed head 1; Control Component 4 is integrated thermistor 41; thermal cut-off 42 and microswitch 43 3 big assemblies are with temperature sense; overheating protection; integrate with interior pot induction three big functions.The contact of described microswitch 43 stretches out in the lower end of Control Component 4, is fixed with the locating piece that triggers microswitch 43 break-makes on the position of corresponding microswitch 43 contacts on the described fixed head 1.
Electric cooker product with the application temperature controller is an example, and the utility model temperature controller is fixed on the outer pot of electric cooker, and the hole of passing heat-generating disc contacts with interior pot bottom.In when pot in not having, movable parts such as the outer cup 5 of temperature controller and Control Component 4 move up under the promotion of spring 2, and the contact of microswitch 43 leaves locating piece, switch closure; When putting into pot, movable parts such as the outer cup 5 of temperature controller and Control Component 4 move down under the pressure of interior pot promotes, the contact contact locating piece of microswitch 43, and switch disconnects.Judge that by the break-make of microswitch 43 interior pot has or not.
The upper surface of the utility model temperature controller contacts with interior pot bottom, by pot temperature in thermistor 41 inductions, controls the process of cooking.
The upper surface of the utility model temperature controller contacts with interior pot bottom, and when product heated unusually, thermal cut-off 42 fusing were cut off the electricity supply, and realize overheating protection.
The utility model temperature controller is applied to similar products such as other electric pressure cooking saucepans, electric food warmer, also can reach same effect.
